- DEVICE FOR SEPARATING OIL FROM WATER.

SPECIFICATION forming part of Letters Patent No. 249,868, dated November 22, 1881.

Application filed October 6, 1881.

To all whom it may concern:

Be it known that I, PETER ANDREW, of Gincinnati, Hamilton county,Ohio, haveinvented a new and useful Device for Separating Oil from Water, of which the followingisaspecification.

The accompanying drawing is avertical section of a tank provided with my invention.

A may represent a tank ot' suitable construction. Fastened to the inner wall of the tank in a vertical position is a wooden tube,B, open at both ends, its lower end within an inch of the tank-Hoor, its upper end at or near the level of the top edge of the tank. Screwed through the tank-side a short distance below the tank-top, and into one side of tube B, is a short iron pipe, O, whose screw-threaded outer end is secured Within a correspondingly screwthreaded L-coupling, D, which, being turned downward, as shown, receives a similar short pipe, E, to Whose lower extremity a perpendicular wooden tube, F, is screwed in the manner shown. The pipe or tube F may discharge. into a drain. The height of insertion of the (No model.)

short pipe O willdepend on the specic gravity of the oil and the height at which it is desired that it shallstand in the tank.

Supposing the tank-to be empty when the mingled oil and Water begins to dow into it, the tank will continue to lill up until the water, (being the heavier ingredient,) having risen in tube B, begins to escape through pipe C, coupling D, pipe E, and tube F, and this escape of the water will continue until oil only remains within the tank. This condition is indicated by appearance of oil at the discharge, which being observed, the supply isstopped.

I claim as new and of my invention- The described arrangement of tank A, wooden tubes B and F, short pipes C and E, and L-coupling D, substantially as set forth.

In testimony ot' which invention I hereunto set my hand.

PETER ANDREW.
